SYSTEM ornunnroa'r on F93 ma den Application filed September 18,1930, Serial No. 4sas9aandin France as aieaa tw voirs arranged in suitable number and at suitable localities on the under frame, and from which distributors branch pipes extend to the members to be lubricated. These distributors are preferably located at such positions that the pipes supplying themhave substantially the same length, so that the losses of pressure may be the same in said pipes, and that the output of oil at the clifferent places to be lubricated by a distributor may be substantially the same.

The invention also relates to certain arrangements of details which will be hereinafter described.

In the accompanying drawings, Figure 1 shows in section through its axis, one'construction given by way of example of a distributor for the lubricant in accordance with the invention. Figure 2 isa diagrammatic showing of the system of lubrication.

On reference to Figure 1 of the drawings it is seen that the distributor or intermediate reservoir is shown at 1. This distributor is preferably composed of an easily removable bell 2 attached upon a dished plate 3. A nozzle 4, communicating with this dis tributor through said plate 3 is connected with the main oil supply, which supplies the different distributors with forced lubrication. For this purpose there may be em ployed a pump driven by hand or electricaL ly, by partial vacuum or in any other way. The lubricant may also be sent directly to the distributors by the oil-circulating pump of the engine. In this case a filter is interposed between the pump and the distributors. Upon the nozzle 4 is fixed a tube 5 perforated with a certain number of holes 6. A valve, for example a ballvalve 7 subjected to the action of an opposing spring 8, whichforcesit on to itsseat 9 providedinside the tube 5, in'certain conditions allows the oil; under pressure coming from the nozzle 4 to pass throughthe holes 6 to the'inw tenior of the bell 2. An auxiliary filter 10 is I located in the tube 5 in front of the valve 7. The nozzle 4' is provided with a passage '11 v of section suitably dimensioned for the supply to the distributor anddeterminedby the locality p of-this distributor, and the pipes which it has to supply. Pipes l2 leading to the places to belubricated are branched off from the distributor 1.. These pipes, in the example shown, are connected by means of adjustable joints 13 to hollow pins 14 fixed c in the dished plate 3 and projectingby a certain amount intofthe interior "of the p distributorn Wicks 15 .placed in the bottom of the dished plate 3 are placed inside, the hollow pins 14, which communicate through the ole 16 w t the? j nt tac to the p s 12. There are provided upon each distri u-- tor l'anumber ofjoints andpipes 12,.corre} spending to the numberof points to'be lubrr cated, The-operation of the apparatus can be readily understood The oil under pressure comingfrom the main supply passes through the nozzle 4, the pipe 5 and theholesfi, lifting the valve? in the distributor, 1. The oil will rise in the distributor to a fixed height and will compress the'air which is aboveit inthe bell 12.;The' oil inpthe distributor will thus be subjected to a certain compression and will be carried over by the wicks 15 to the holes 16 in thepinsf'l4 and to t e pipes12 leading to the members to belubricated. I The main supply comprising the pump intended to send the lubricant under pressure, or to control the flow of oil from the engine to thedistributors, is attached to the vehicle within reach of the driver. The distributors are disposed on the underframe at places suitably selected so that each of themlubri- 1 catesa group of members adjacentto each other as diagrammatically. indicatedin Fig. ure 2; the pipes connecting the distributor with the different memberswhich it supplies have; preferably approxiinately the same iron the same height. V the loss of pressure may be the same for the length and are arranged as far as possible at Care should be taken that different pipes. The regulation of the supply might evidently be efiected in the several pipesjby determining in a suitableiway the section ofthe oil-passage'ineach of them.

' Figure 2 shows an application of the lubricating systemapplied to a motor vehicle. As shown'a main oilreservoir is oper'atively connected with a pump actuated by a pedal M, near the foot of the operator of the automobile. Pressure upon this pedal forces oil through-the pipes'M', to the distributors O and P from which oil is driven throughthe pipes M, to the points A, B, C, D, E, F, G,

from the distributors O, and to the points I, J, K, from-the distributors P. It is to be clearly understood that this system of lubrication may be employed for the lubrication of any plant includinga plurality of mechanicalmembers to be lubricated.
